Use VBEP, VSP, VS3P, VCP, VP2 bonds on wide contact areas where heat is an issue. Multi-Point Diamond Tools Most multi-point tools are used for straight face dressing Tool should have full face contact with the wheel With new tool, 3 to 5 passes at.005" per pass should be taken to expose diamonds Infeed per pass.001" -.002" Use coolant whenever possible Use appropriate lead (and traverse rate) Contact your Norton representative for proper tool selection for Targa (TG) wheels It is the user s responsibility to refer to and comply with ANSI B7.1 Dressing Ceramic Wheels Use our specially designed Norton SG diamond tools when dressing ceramic wheels When first using a Norton SG tool, make 3 to 5 passes at.005" infeed to ensure full face contact between the dressing tool and wheel face Reduce normal dressing infeed by half. Do not exceed infeed of.002" per pass. The lead selection should be between.006" -.030" per wheel revolution. Faster traverse with Norton SG tools generally provides an open wheel face that can maximize productivity of the ceramic abrasive. To optimize applications using ceramic abrasives and/ or tools, normal dressing parameters must change. Reduce infeed by 25%. Significant reductions in the amount of infeed and frequency of dress will result in substantially lower cost per part ground.

5 TROUBLESHOOTING GUIDE PRECISION PRODUCTION ABRASIVES TOOLROOM VITRIFIED WHEELS Check the obvious first. Before changing the grinding wheel specification, investigate the following most common causes for most grinding problems: 1. Diamond dressing tool condition (check if worn or dull, rotate tool or replace if necessary) 2. Coolant direction, volume and filtration 3. Wheel dressing procedures (dress more open to free up cut rate, dress more closed to improve finish) PROBLEM POSSIBLE CAUSE CORRECTION Workpiece burn Poor coolant direction Redirect coolant into grinding zone Restricted or low coolant volume Increase coolant volume Wheel too hard Use one grade softer wheel Wheel structure too closed Use porous bond wheel Wheel dressed too fine Dress wheel coarser, more open Worn dressing tool Inspect, rotate or replace dressing tool Work speed too slow Increase work speed Infeed too fast Reduce stock removed per pass or upgrade to 5SG or 5NQ Wheel loading and glazing Wheel too fine Use coarser grit or softer grade wheel Wheel too hard Use one grade softer wheel Too durable abrasive Use a sharper, more friable abrasive Poor coolant quality Change coolant or use high detergent type Wheel structure too closed Use a porous bond wheel Wheel too finely dressed Dress wheel very open Diamond dressing tool worn Replace diamond and dress coarse (open) Depth of cut too small Increase feed and traverse speed Chatter Unsupported work Increase work support Machine vibration Check for worn bearings Too heavy cut rate Reduce cut rate Wheel too hard Use one grade softer wheel Wheel structure too closed Use a porous bond wheel Wheel out of balance Check wheel balance or try new wheel Chatter marks on workpiece Worn spindle bearings Check and correct for truth and end play Wheel out of truth Redress wheel and check mounting Poorly clamped wheel Check tightness of mounting nuts Glazed face of wheel Redress wheel with sharp dressing tool Poor surface finish Incorrect wheel dress Dress wheel finer (slow down dressing tool traverse) Worn dressing tool Inspect, rotate, or replace dressing tool Too coarse grit size Use a finer grit size Wheel too hard Use softer grade Not holding form Wheel too soft Use one grade harder wheel Wheel structure too open Use a more closed wheel structure Not holding corner Incorrect wheel dress Dress wheel finer. Face and side true wheel.

TECH TIP Proper Wheel Mounting 1. Thoroughly clean spindle and flange bearing area of all dirt and foreign material. 2. Inspect for worn, distorted or damaged areas on flanges and spindle. 3. If mounting a wide centerless wheel on a spindle (i.e., twin-grip), do not use grease or other petroleum lubricants. Use a silicone spray lubricant on the spindle to ease mounting the wheel, if necessary. 4. Ensure mount up arrow is at the top of the wheel. In the case of butted sets, assemble so that the arrow is formed across the top of the wheel face. 5. Ensure proper blotters are installed; one on each flange mating surface. Always use new blotters. 6. Install blotter flange and snug up the bolts only finger tight. 7. Using a torque wrench, tighten all bolts in an alternating pattern from side to side to 15 foot pounds. 8. Repeat the same tightening sequence, increasing the torque to 35 foot pounds.» for wide wheels (18"-20"), torque the bolts at 45 to 50 foot pounds» for narrower wheels (2"-12"), a torque of 35 foot pounds is sufficient 9. Retorque the flange bolts to specification after the first eight hours of operation.
